Abstract

A wideband vector channel sounder with 16 parallel RF chains is proposed for parameter estimation in an indoor channel. Low‐cost and high‐resolution are obtained by using a chirp probe signal, five‐port receivers and the MUSIC algorithm. The system covers up to 500 MHz centred at 2.45 GHz. Experimental results show errors inferior to 1 ns in the time domain and of few degrees in the angular domain. Accurate results are found in static as well as in time‐variant scenarios.
